What prep is needed for new subdomain with Exchange 2003 with root domain that has been 2010 preped.
Hi, Completing an install on an island in the south pacific ocean with 500kb satellite coms.... so would prefer to be on the beach than in the office ! I am having trouble creating the RUS for a new subdomain. Our environment is a 2008 R2 Functional level Root domain with one subdomain with mail enabled users. There is an Exchange 2003 server in the root domain. The root domain and one current subdomain has has been Prepped for Exchange 2010 (but Exchange 2010 is not yet installed). (When I installed the first subdomain I run Exchange 2003 domain prep on it from a 2003 server, at a later date I ran the Exchange 2010 Prep for Forest and domains) This thread is related but can't run any command from root domain as it says there is no RUS for the subdomain- http://social.technet.microsoft.com/Forums/en/exchangesvrgeneral/thread/d625484d-c32b-4ef5-92e0-854dda804acc I've added a new sub domain (2008 R2 Functional level), so now two subdomains. I only brought with me the Exchange 2010 ISO. So I prepped the new domain with Exchange 2010 with no errors...... Problems: · Exchange 2003 server can't create the RUS for the new domain... When try to manually create the RUS it says run \domainprep on the subdomain (which I have done with Exchange 2010). · Can't ran Exchange 2010 domain prep from Root domain as it says it can't find the RUS for the domain (and server is pending a reboot (???)) So do I need to in the new subdomain? : · Install a 2003 server in the new sub domain, (As Exchange 2003 is not compatible with Server 2008 R2). · Run Exchange 2003 /domainprep. · Run Exchange 2010 /PrepareDomain Do I need to do any Schema/AD prep in the root domain that then applies to the new subdomain or has the previous prepping of AD applied to the new subdomain when it was created? (downloading Server 2003 and exchange 2003 now.... overnight job !) Thanks heaps for any help / advice :-))))

Sounds like you haven't run the legacy permissions prep. http://technet.microsoft.com/en-us/library/aa997914.aspx Simon.Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK? Hire Me.
